IMPROVEMENT IN CORN-PLATBRS.

TO ALL WHOMIT MAY CQNGERN: i.

Be it known that I, J. M. ALLSON, of Cranberry, inthe county of Venango,and State ofV Pennsylvania, Y

have linvented 'a new and useful Improvementin Gern-Planter; and I do hereby-declare that-the following is .a full, clear, and exact description thereof, whichwill enable others skilled in thelart to make and use 'the same, reference being had to the accompanying drawings, forming part of this specification.

Figure 1 is a top view of my improved corn-planter. i Figure 2 is a side view of the same, part being broken away to show the construction. Similar letters of reference indicate corresponding parts. l My invention has for its object to furnish o. simple, convenient, and eective machine, by Vmeans of which corn may be dropped accurately and rapidly by hand-power; and it consists inthe construction and combination of the various parts,a.s hereinafter more fully described.v

A is the frame of themachine, B is the axle', and C is the wheel, all of which are similariin construction l and arrangement to the frame, axle, and wheel of anordinary whee1-barrow, exe'pt that the surface of the wheel C has cogs or projections formed upon it, to enable it to takes surer hold upon the ground, and prevent its slipping. D is the bed-plate, which is attached to `the side bars of the frame A.

The end parts of the bed-plate D are cut away ,to receive the hoppers E, which are hinged at their rear sides .i to the rear part ofthe lbed-plate D.

Fis a gauge-slide, forming the forward part of the bottom the hopper, the Aedge-s of which slidein grooves formed in the sides of the hoppers, so that it may be adjusted to allow any desir ed amount of corn to pass out at a time.

G is a slide-board, sliding in grooves in the sides ofthe hoppers Ebeneath the bed-plate D, and whichis4 of such a length thatits ends may project in front and rea'r of Asaid bed-plate, as shown iii the drawings.

.The rear part of-the slide Gis slotted, as shown in lig. 2,through which slot, when the said slide is pushed forward, the corn drops to the greund. v f

To the rear end of each of the slides G is pi'voted a small friction-roller, H,ias` shown in figs. 1 and 2, for the arms or cams I, formed upon orattached to the ends ofthe shaft d, to act upon, to push the said slides forward to drop the corn. i I v To the rear ends ofthe slides G are attached upwardlyprojecting pins or arms, K, ngninst'which .the free ends of the springs L rest, to push the seid slides hnckwhen released from .the arms orcauis I. The other ends of the springs L are attached to the' block M, which is secured to the frame A., f i

The shaft J revolves in bearings'in the frameA, 7and to its middle part is'attacheda gearwheeh N, the

teeth of which mesh into the teeth of the gear-wheel O, formed upori or, attached to the sideof the drive=wheei G, so that` the dropping slides G may be operated 'to drop the corn by the advance ofthe machine.

' The circumference of the drive-wheel C should equal the distance whichithe hills nre desired to be apart, and the hoppers Eshould be at the samedistance apartysothatthecorn may beplanted in checlbrow.

When the machineis in operation, the hoppers are braced against the pressure of the arms or cams I by the bracerods P, one end of whichis pivoted tothe side of the-hopper, and theother ends of which have eyesformedupon them, 'which pass over pins Q, attached to the side of the frameor handles A, s as to securely'bracethe hoppers in place.

R is another set of pins, placed a little in the rear of the pins Q, so that by hooking the ends 'of the bracerods P upon the pins R, the hoppersE will be held up, so that the arms or cams I cannot strike the slidesG. This enables the machineto be moved from placeto place without operating the said slides G. i

S is a rod, the inner end of which is swivelled to the rear edge of the middle part of the bed-plate D, and the forward end of which is bent down, so that when extended to the side of the, frame A, as shown in figs. 1 and2, it may serve as a guide in returning,'and cause all the rows to .be at the-same distance apart T are stops or guides attached to each side of the frame A, so as to hold the said rod S in place when turned to -eithei` side.

U are open boxes attached `to the under side of the .bed-plate, to guide the corn as it drops to the ground.

Further security 'against the seeds being scattered or blown out of place may be obtained by ttaclingfnn open sack, V, to the' lower end of each of the'l open boxes U, asshown in fig. 2. 'I

I claim as new, :md desire to secure by Letters Patentf 1. The combination of the gear-wheelsO and N, shaft J, cams or arms I, slotted slides G, and'springs L, with the drivewheel C, frame A. andhoppers-E, substantilly as herein shown and desoribed, and for.tlie,pur' pose set forth.4

A2. The combination of the adjustable slide bottom F with the hoppersvE `and slotted slide G, substantially as herein shown and described7 and for the purpose set forth.

J. ALLISON.
